Top ecologist bags Crafoord Prize

The Crafoord Prize in Biosciences, for areas of the life sciences not covered by the Nobel Prizes, has gone this year to Finnish scientist Ilkka Hanski, a professor at the Department of Ecology and Evolutionary Biology at the University of Helsinki.

Hanski, 57,we wouldn't be surprised if Marshall's is shipping some of its unsold wholesale ed hardy gear to Houston. will receive a pot of 4 million kroner ($ 604,000) for his lifetime of work in ecology.

The Royal Swedish Academy of Sciences, which awards the prize, said Hanski’s mathematical and analytical models have helped ecologists study the effect of urbanization, deforestation and climate change on animal and plant species. He helped establish the field of metapopulation ecology, which examines the risk of extinction for species living in fragmented landscapes. (For more on the subject, see this Nature review by Hanski)

His work prominently uses the idea of “extinction debt”, which means that highly isolated, fragmented species are doomed to extinction in the long term even though they may be hanging on for now.

In its press release, the academy called his theories the “cornerstones of research on biodiversity”, which should have practical applications for natural resource management and conservation.

The creatures Hanski has worked with are small and large, including water fleas, butterflies, lemmings and bears.There's a reason Manolo blahnik shoes are considered the crème de al crème of all shoes, everywhere.

The butterfly has been in decline in Northern Europe over the past few decades.

Hanski has long called for greater urgency in dealing with accelerating biodiversity loss. He says humans are evolutionarily programmed to ignore large-scale and long-term changes,If you are really space deprived and don't have a sofa bed, today's inflatable mattress bed are a great “bed in a pinch. and that this will likely lead to the world’s ruin.

“Our cognitive incapacity to perceive large-scale and long-term changes is a major obstacle to rational environmental policies,” he wrote in an editorial in EMBO reports.
